not exactly sure how often since the autocast for the stations lightning strike doesnt work so i rarely test/see it (should have mentioned that too)but as mirogog mentioned it is understandable that you wouldnt notice it as IN since its the chaos station that uses the IN teleportation FXas seen in the screenshot my station is doing a teleport at that emperor and its using the blue IN fx not the red chaos onenot sure if orks or eldar have the right one, tau use a similar one as IN i think so that shouldnt be a problem either way
